Police said he was not stabbed or shot, but they don't know yet how he died.

"The only thing we can throw out there possibly he was hit by a car, hit and run. Where he was found there's also a hillside. I guess it's a possibility that he fell down that hill," Sgt. Jeffrey Kennedy said.

The Allegheny County medical examiner identified Ferrero on Saturday. Police said was formerly of Scott Township, but had been living at the Extended Stay America hotel on North Bell since November.

Why Ferrero moved to the hotel is still unknown to police, but Kennedy said Ferrero did not have a criminal history in Carnegie and hotel managers told police they had no problems with him.

"Our officers did find a shoe in the bushes where the body was found," Kennedy said. "We're not sure if that shoe came off as a result of a car accident or maybe from falling down a hill. We're not sure of that at this time."

With no witnesses, how he died remains a mystery. An autopsy is scheduled for Saturday.

"That particular section where he was found is very dark. It gets more lit up in the office park, but that section is very dark and it's not very heavily traveled," Kennedy said.
